Re: Inverting, 0 -> 1 and 1 -> 0

If you're trying to invert opacity, just subtract the value from 100.

In general though, if you want to convert one range of numbers to another, you can use the linear() method. For example, if "x" represents the value you want to convert, for opacity you could use something like this:

invertedX = linear(x,0,100,100,0);

Or, as you suggest, you could use it to invert 0 to 1:

invertedX = linear(x,0,1,1,0)

It's pretty versatile.
